Medical News Today -- It's a familiar scene on most TV medical dramas: a patient is unconscious; CPR didn't work; someone yells, "All clear!" and the defibrillator paddles are applied to the person's chest in hopes the electric current shocks the heart back into action. In real life 350,000 Americans die of sudden cardiac arrest every year because they don't have implantable devices or defibrillators nearby at the time of the cardiac arrest.
